The light bulb will have the same mass on the moon as it will on earth. The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. For instance, if you measure your mass on Earth and then measure your mass on the moon, your mass will remain the same. The same theory applies to any object with mass.
yes, why because earth has gravity and the moon does'nt so just think that if you were the light bulb you would flout and the mass goes away the mass id the gravity so your answer is yes the mass would changes as it travels
